Application of Production Analysis Method in Qiang1-46-20

摘要

Production data (pressure and flow rate) contain a large amount of reservoir information. At present only simple production decline analysis with Arps equation has been applied by analyzing production data which do not play an actual role. Production data can be applied to analyze formation capacity, determine the amount of geological reserves, surplus reserves, recovery, time at abandonment, value of abandonment rate, cumulative volume at abandonment time etc. Production data also can be applied to simulate changing history of well drainage area and formation pressure distribution in order to predict production and effect of measurement. And the parameters similar to well test interpretation results also can be derived. To some extent, production analysis can replace buildup test. In this paper the principles and methods of production data analysis technology have been introduced, and the practical application in Liaohe oilfield also has been shown.
